>>33195752>creatures based on creatures from the real worldIt's a mystery where the animal name classifications came from
>berries based on fruits from the real worldSome material in-game suggests that Berries are Pokemon food. Some material in the anime suggests berries and real life fruit co-exist.
>regions based on locations from the real worldThey need to retcon the Pokedex and some dialogue in older games. Worldbuilding makes it look foolish, now.
>character outfits based on outfits from popular people or popular animationsAudrey Hepburn is one, but I think that's the only one the fanbase is in agreement about. The rest are debatable (i.e. Elesa being based on Lady Gaga is reaching, considering she's just borrowing from experimental fashion shows)
